A more common reason is that a user admin has blocked ssh/rlogin as a root
account. For root access, one must access at a lower permission level, and
then elevate permissions as needed using su. This reduces an attackers
ability to gain access to the root account, and helps prevent mindless root

@vishal - the su command is just "switch user". The sudo command means
"execute a command as that user".

how to breakubuntu's root password?
(06 Apr 2010, 01:01
code: "su - root"
It will ask for the password for root.
code: "xxxxxxxxxx" <--use your root password.
If the password was correct..the prompt will change from a "$" to a "#".
You now have the power to destroy your system. :)
